本申请要求享有2017年9月29日提交的中国专利申请No.201710907613.7的优先权,其全部公开内容通过引用并入本文。
本申请涉及显示技术领域,具体地,涉及一种用于印刷玻璃胶的刮刀、包括刮刀的用于印刷玻璃胶的装置以及利用该装置印刷玻璃胶的方法。
玻璃胶是制造显示面板时使用的封装材料,例如,在封装有机发光二极管(Organic Light Emitting Diode,OLED)器件时,需要将玻璃胶印刷到OLED器件的基板上。用于印刷玻璃胶的装置通常包括刮刀。在印刷玻璃胶时,首先将玻璃胶涂覆到印刷掩模板的图形区域(即,印刷掩模板上形成有开口的区域)中,然后再利用刮刀将印刷掩模板的图形区域中的玻璃胶印刷到基板上。
相关技术中使用的刮刀的用于印刷玻璃胶的边缘通常被设计为一条直线,并且刮刀在所述边缘上的硬度处处相同。印刷掩模板上的开口可以形成为具有矩形形状,从而印刷后的玻璃胶具有对应于开口形状的矩形形状。
发明内容

根据本申请的一个实施例,所述一组骨架支撑结构中的两个骨架支撑结构之间为第一距离,所述第一距离等于用于印刷玻璃胶的印刷掩模板上的开口的宽度。
根据本申请的一个实施例,两组相邻的骨架支撑结构之间为第二距离,所述第二距离等于所述印刷掩模板上的相邻开口的相邻边之间的距离。
根据本申请的一个实施例,刮刀主体的嵌入有所述骨架支撑结构的部分为第一部分,没有嵌入所述骨架支撑结构的部分为第二部分。所述第一部分的硬度为第一硬度,所述第二部分的硬度为第二硬度,所述第一硬度大于所述第二硬度。
根据本申请的一个实施例,第二硬度的范围可以为40至60。
根据本申请的一个实施例,刮刀主体的厚度范围可以为8mm至15mm,并且其中,骨架支撑结构的厚度范围可以为6mm至12mm。
根据本申请的另一方面,提供一种用于印刷玻璃胶的装置,包括印刷掩模板、刮刀和印刷台。刮刀可以包括根据上述任一实施例的刮刀。
根据本申请的另一方面,提供一种印刷玻璃胶的方法,利用根据本申请的用于印刷玻璃胶的装置执行该方法。该方法包括步骤:将玻璃胶涂覆到印刷掩模板的图形区域;以及利用刮刀将玻璃胶透过印刷掩模板的图形区域中的至少一个开口印刷到印刷台上的承印物的表面,其中,嵌入在刮刀的刮刀主体中的至少一组骨架支撑结构中的两个骨架支撑结构与所述至少一个开口的在刮刀的运动方向上延伸的两条边分别对齐。
根据本申请的一个实施例,在利用刮刀将玻璃胶印刷到承印物的表面的步骤中,刮刀的刮刀主体与印刷掩模板的表面之间的夹角小于90°,并且刮刀主体向刮刀的运动方向倾斜。
根据本申请的一个实施例,在利用刮刀将玻璃胶印刷到承印物的表面的步骤中,刮刀主体的第一边缘与印刷掩模板的表面接触。
为了更清楚地说明本申请各个实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍。显而易见地,下面描述中的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些图获得其他的附图。在附图中:
图1示意性地示出了根据本申请的一个实施例的刮刀;
图2示意性地示出了包括根据本申请的一个实施例的刮刀的用于印刷玻璃胶的装置;以及
图3示意性地示出了利用根据本申请的用于印刷玻璃胶的装置执行印刷玻璃胶的方法的流程图。
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述,显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本申请保护的范围。
附图中各部件的形状和大小不反映真实比例,目的只是示意性地说明各个实施例。
在实际的生产过程中发现,印刷后的玻璃胶的平行于刮刀的所述边缘的两条边的高度小于垂直于所述边缘的两条边(即,在刮刀的行进方向上的两条边)的高度,从而使得最终得到的产品的机械强度降低。
本申请旨在至少解决相关技术中的上述技术问题。提供一种使得印刷后的玻璃胶在各处的高度更加均匀的刮刀、包括刮刀的装置以及利用该装置印刷玻璃胶的方法。
图1示意性地示出了根据本申请的一个实施例的刮刀。
参见图1,根据本申请的一个实施例的刮刀100可以包括刮刀主体1和嵌入在刮刀主体1中的至少一组骨架支撑结构。所述一组骨架支撑结构包括两个骨架支撑结构2。刮刀主体1可以包括用于印刷玻璃胶的第一边缘1a。骨架支撑结构2在垂直于刮刀主体1的第一边缘1a的方向上延伸。所述第一边缘1a覆盖所述骨架支撑结构2,使其不通过所述第一边缘暴露出来。
根据一个本实施例,在刮刀的刮刀主体1中增加了骨架支撑结构2。刮刀主体1的嵌入有所述骨架支撑结构2的部分为第一部分,没有嵌入所述骨架支撑结构2的部分为第二部分。所述第一部分的硬度为第一硬度,所述第二部分的硬度为第二硬度,并且所述第一硬度大于所 述第二硬度。在印刷玻璃胶时,刮刀主体1的嵌入了骨架支撑结构2的第一部分的变形量相对较小,而没有嵌入骨架支撑结构2的第二部分的变形量相对较大。因此,在印刷玻璃胶时,由于所述第一部分和所述第二部分的变形量不同,使得所述第一部分和所述第二部分相对于印刷掩模板的上表面形成的工艺角度不同,最终实现对玻璃胶印刷高度进行调节的效果。
具体而言,刮刀主体1的嵌入有骨架支撑结构2的第一部分因其变形量较小,使得与所述骨架支撑结构2相对应的位置处的玻璃胶受到的压力较大,从而可使得此位置处的玻璃胶印刷高度降低。
根据本申请的一个实施例,没有嵌入骨架支撑结构2的第二部分的第二硬度(即,用于实现刮刀主体1的材料的洛氏硬度)的范围可以为40至60,从而在印刷玻璃胶时能够产生相对较大的变形量。此外,用于形成骨架支撑结构2的材料可以包括金属、橡胶和高分子材料中的任一项,但本申请不限于此。硬度较高、不易变形并且能够与用于形成刮刀主体1的材料(例如,橡胶)紧密接合且不易分离的任何材料都可以用于形成骨架支撑结构2。
根据本申请的一个实施例,刮刀主体1的厚度范围可以为8mm至15mm,嵌入至刮刀主体1的骨架支撑结构2的厚度范围可以为6mm至12mm。
图2示意性地示出了包括根据本申请一个实施例的刮刀的用于印刷玻璃胶的装置。
参见图2,根据本申请的一个实施例的用于印刷玻璃胶的装置可以包括印刷掩模板200、刮刀100和印刷台(图中未示出)。刮刀100可以为根据上述任一实施例的用于印刷玻璃胶的刮刀。印刷掩模板200上可以形成有矩形形状的开口201。
根据本申请的一个实施例,刮刀100的刮刀主体1中嵌入至少一组骨架支撑结构,所述一组骨架支撑结构包括两个骨架支撑结构2。一组骨架支撑结构中的两个骨架支撑结构之间为第一距离D1,所述第一距离D1等于印刷掩模板200上的开口201的宽度W。两组相邻的骨架支撑结构之间为第二距离D2,所述第二距离D2等于印刷掩模板200上的相邻开口201的相邻边之间的距离d。由于骨架支撑结构2具有一定的宽度,计算两个骨架支撑结构之间的距离时,可以计算两个骨架 支撑结构的中线之间的距离。当然,由于实际制作工艺中产生的误差,上述计算在可允许的误差范围内即可。
相关技术中,印刷后的玻璃胶的平行于刮刀的边缘的两条边的高度小于垂直于刮刀的边缘的两条边(即,在刮刀的行进方向上的两条边)的高度,从而使得最终得到的产品的机械强度降低。在采用了包括根据本申请的刮刀的用于印刷玻璃胶的装置中,由于在刮刀100的刮刀主体1中嵌入了骨架支撑结构2,因此使得刮刀的嵌入有骨架支撑结构的部分在印刷玻璃胶的过程中产生相对较小的变形量,而没有嵌入骨架支撑结构的部分在印刷玻璃胶的过程中产生相对较大的变形量。通过这种设置,可以使得在刮刀的行进方向上的两条边的玻璃胶的高度降低,最终实现对玻璃胶印刷高度进行调节的效果。具体而言,如图2所示,可以将嵌入在刮刀100的刮刀主体1中的至少一组骨架支撑结构中的两个骨架支撑结构2与开口201的在刮刀100的运动方向上延伸的两条边分别对齐,从而使得在这两条边处形成的玻璃胶的高度降低。这里所说的对齐可以理解为骨架支撑结构的中线与开口的在刮刀的运动方向上延伸的边对齐。
图3示意性地示出了利用根据本申请的用于印刷玻璃胶的装置执行印刷玻璃胶的方法的流程图。
参见图2和图3,根据本申请的一个实施例,一种印刷玻璃胶的方法包括步骤:将玻璃胶涂覆到印刷掩模板200的图形区域;以及利用刮刀100将玻璃胶透过印刷掩模板200的图形区域中的至少一个开口201印刷到印刷台上的承印物的表面。嵌入在刮刀100的刮刀主体1中的至少一组骨架支撑结构中的两个骨架支撑结构2与所述至少一个开口的在刮刀100的运动方向上延伸的两条边分别对齐。
根据本申请的一个实施例,在利用刮刀100将玻璃胶印刷到承印物的表面的步骤中,刮刀100的刮刀主体1与印刷掩模板200的表面之间的夹角小于90°,并且刮刀主体1向刮刀100的运动方向倾斜,以形成小于90°的夹角。在印刷玻璃胶时,由于刮刀主体1的嵌入有骨架支撑结构2的第一部分的变形量较小,而刮刀主体1的没有嵌入骨架支撑结构2的第二部分的变形量较大,并且以小于90°的倾角来使得刮刀100在运动方向上行进,从而使得所述第一部分和所述第二部分相对于印刷掩模板200的上表面形成的工艺角度不同,最终实现 对玻璃胶印刷高度进行调节的效果。具体而言,所述第一部分相对于印刷掩模板200的上表面形成的第一工艺角度大于所述第二部分相对于印刷掩模板200的上表面形成的第二工艺角度。
根据本申请的一个实施例,在利用刮刀100将玻璃胶印刷到承印物的表面的步骤中,刮刀主体1的第一边缘1a与印刷掩模板200的表面接触。
在印刷玻璃胶时,根据本申请的刮刀的刮刀主体的没有嵌入骨架支撑结构的部分(即,第二部分)的变形大于嵌入有骨架支撑结构的部分(即,第一部分)的变形,从而使得印刷后的玻璃胶在四个边处的高度更加均匀,增加了最终得到的产品的机械强度并且提高了产品的性能。
以上各个实施例仅用以说明本申请的技术方案,而非对其进行限制。尽管参照前述实施例对本申请进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各个实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换都属于所附权利要求书所要求保护的范围。
